Ending the Chase: AI Pre-Payment Audits Save Medicare Advantage Millions

BOSTON, MA – November 04, 2026 — In the sprawling, high-stakes ecosystem of American healthcare, the most expensive inefficiencies are often the most deeply entrenched. For decades, health insurers have relied on a "pay and chase" model for payment integrity, issuing reimbursements to providers and subsequently deploying armies of auditors to claw back overpayments. It is a retroactive, resource-heavy approach that breeds resentment and administrative bloat. But as the financial guardrails of Medicare Advantage continue to tighten, the industry is being forced to pivot.

Today, Boston-based health-tech firm Cohere Health announced a milestone that underscores this operational shift. Utilizing its AI-powered pre-payment clinical review program, an unnamed Medicare Advantage client identified more than $10 million in savings over a six-month period. The platform targeted complex clinical and coding errors in high-cost specialty drug and durable medical equipment (DME) claims before a single dollar was disbursed.

Achieving a 48% finding rate on targeted claims with an appeal rate below 2%, the results offer a compelling glimpse into the future of claims adjudication. For professionals tracking the macro-trends reshaping healthcare finance, the message is clear: the era of algorithmic, pre-payment auditing has arrived, bringing with it a profound realignment of payer-provider dynamics.

The Financial Imperative in Medicare Advantage

The pivot toward proactive payment integrity is not merely a technological upgrade; it is an economic necessity. Medicare Advantage now covers more than 55% of all eligible Medicare beneficiaries, representing over 35 million individuals. As enrollment has surged, so too has federal scrutiny. In fiscal year 2025, improper payments in Medicare Advantage (Part C) reached an estimated $23.67 billion. In response, the Centers for Medicare & Medicaid Services (CMS) significantly expanded its oversight, committing in May 2025 to audit every eligible Medicare Advantage contract annually.

Coupled with surging costs for specialty pharmaceuticals and tightening federal reimbursement benchmarks, Medicare Advantage plans are operating under unprecedented margin pressure. Traditional post-payment audits, while historically lucrative, are increasingly viewed as a liability. They require immense human capital, delay final financial reconciliation, and trigger a cascade of provider appeals that erode trust and consume administrative resources.

Healthcare executives privately concede that the old model is no longer sustainable. Recovering funds months after they have been spent is inherently inefficient, particularly when dealing with the complex, high-dollar claims associated with specialty drugs and DME. By shifting the intervention upstream, health plans are attempting to staunch the bleeding before it occurs, effectively turning payment integrity from a retroactive recovery mechanism into a real-time financial firewall.

Flipping the Script on 'Pay and Chase'

Cohere Health’s approach leverages its Cohere Validate solution, an AI-powered tool integrated into the broader Cohere Unify platform. Bolstered by the company's September 2025 acquisition of ZignaAI, the system moves away from rigid, traditional rules engines. Instead, it deploys precision AI agents that analyze the full claims population in near-real-time, isolating claims with a high probability of clinical or coding discrepancies while allowing clean claims to process without delay.

When a complex claim is flagged—such as a heavily coded durable medical equipment request or a novel specialty therapeutic—the AI synthesizes clinical evidence generated across the care-to-payment lifecycle. It then surfaces the claim for human clinical review, ensuring that no denial is generated exclusively by an algorithm.

"Modern payment accuracy should be about identifying the right claims early, supporting decisions with clear clinical evidence, and doing so without creating more burden for providers and health plan teams," said Lalithya Yerramilli, SVP of payment solutions at Cohere Health. "That's what transparent, clinically grounded review workflows make possible."

The reported 48% finding rate on these targeted, high-cost claims highlights the precision of agentic AI models compared to traditional sampling methods. Rather than auditing a random cross-section of claims, the technology acts as a targeted forensic tool, identifying the "hidden costs" of coding bloat and clinical misalignment before they hit the ledger.

The Low-Abrasion Promise

Perhaps the most striking metric in Cohere Health's announcement is not the $10 million saved, but the appeal rate of less than 2%. In the contentious world of healthcare billing, provider abrasion is a massive, unquantified hazard. Aggressive denial strategies often result in a flood of appeals, forcing both payers and providers into costly administrative warfare.

Industry analysts note that maintaining positive provider relationships has become a critical vulnerability for health plans. When algorithms indiscriminately deny claims, physician cash flow is disrupted, and trust evaporates. To mitigate this, Cohere’s platform ensures that every determination traces back to a clear, citable source. Whether it is a specific CMS guideline, a plan-specific policy, or a contractual term, the rationale is provided directly to the billing department.

This transparent, evidence-grounded approach appears to be the key to neutralizing provider friction. By providing a specific, understandable rationale for a pre-payment flag, the system transforms a traditionally adversarial interaction into a clinical dialogue. Furthermore, the mandatory human-in-the-loop oversight acts as a vital safeguard against the algorithmic bias and hallucination risks that have plagued earlier iterations of healthcare AI.

Algorithmic Auditing and the Future of Claims

The success of Cohere Health’s MA client is a microcosm of a much larger industry transformation. The global healthcare payment integrity market, valued at over $15 billion in 2025, is projected to double by the early 2030s. Pre-payment review already captures nearly 43% of this market share, driven by rapid advancements in cloud computing and machine learning.

As capital continues to flow into this space—evidenced by Cohere’s own $90 million Series C funding round in May 2025—the competitive landscape is intensifying. Legacy giants like Optum and Cotiviti are increasingly competing with agile AI challengers to define the future of claims adjudication. The architectural shift from basic automation to agentic AI means that platforms can now read, interpret, and cross-reference vast amounts of unstructured medical data against complex regulatory frameworks in milliseconds.

However, the rapid deployment of these technologies is not without its hazards. The reliance on AI to dictate payment introduces systemic risks if the underlying models are flawed or if clinical oversight is marginalized in the pursuit of efficiency. The challenge for health enterprise architects and policymakers will be ensuring that these systems remain transparent, equitable, and strictly tethered to clinical reality.

For now, the transition from retroactive clawbacks to proactive, AI-driven pre-payment review represents a rare convergence of financial prudence and operational efficiency. As Medicare Advantage plans navigate an era of tightening margins and heightened regulatory scrutiny, the ability to identify and correct billing errors before the check is cut is no longer just a competitive advantage; it is a fundamental requirement for survival in the modern healthcare economy.
